IMPROVEMENT IN MILK-SHBLVIIS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM-VEDER, Jr., of Shingle Creek, in the co'untyiof StlLawrence, and State of New York, have invented a new :md improved Milk-Shelf; and I do hereby declarethat the following is a full clear, and exact description thereof, which will enable Athose skilled inthe art to make and use the'same, reference being had to the accompanying drawings, forming part of this speciication.

This invention relates to a. new and improved method'of constructing shelves for setting milk, so 'esto allow the cream to rise for making butter.

It is a fact with which the manufacturers of butter are familiar, that a'urrent'of air is necessary to keep the milk a'z'the proper 'temperature in order to produce thegreatest quantity of cream; but it is also well known thatif a current of air is allowed to comev i'ncontactwith the surfaceof the milk, a tough coating on the cream is produced.v whichit. is lvery ditiicult, if not impossible, to reduce to butter. This'coating breaks up in the process o'fchurning, andforms what are known as white cops, a portion of which goes olf with the buttermilk,A

and aiiother'portiou goesinto the butter., lhislatt-er portion is very damaging` to the butter. Much of the frowy'or strong 'butter in market is produced thereby.

I To avoidthis difculty,:and to devise means for Vproducing creamjot" uniform quality, I providetubular shelves with suitable orificesl in which to set the pens, whereby a current of cool air is made to 'circulate around the pans of milk lwithout coming in contact with 'the surface, and in this my invention consists.'

I Figure 1 is asectional elevation or side View of two tubular milk-shelves-arranged according to my invention, thesectionl being through the line :r :c of iig. 2.

Figure 2 is a top view of one of the shelves. Similar letters -of reference' indicate corresponding parts.

A represents .the tubular shelf, which is a square box' oitube open at each end, as seeu in theA drawing,

which ends pass through thesidcs of the milk-house 'or building; B represents tbe'walls or sidesoi' the building in which the shelves are placed u C represents the top ofthe-tubular shelf. D represents orifices through this top. C, of size or diameter-suicient to receive thepans sothat theyr'nay be suspended and'sustaincd therein.

The pans maybe ot" such size or diameter that they will drop down to near their upper edge or rim,'if desired, so that the'bottom and sides will be exposed tothe currentfof air which will circulate through the tube,

while the surface of the milk will be protected therefrom.

Doorsor shuttersV may be attached to thefeuds ci -the tube, to exclude the air in whole or in part, wher v deemed necessary. v

I 'claim as new, and desire'lto vsecure by Letters Patent- The tubular shaft A, arrangcdgwithreference tofthe milk-pans andA the buildingor milk-house, substantiall as shown and described, for the purposesset forth. i Y
